Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or

Introduction
This document is one of a series under the general title "Houses — Description of performance". The
objective of the ISO 15928 series is to identify the methods used to describe the performance of houses.
The ISO 15928 series is confined to buildings occupied for residential purposes that may be separated
or linked horizontally, but not linked vertically, and which have their own access and do not share any
common space.
Each part of the ISO 15928 series relates to a separate attribute. ISO 15928 (all parts) do not specify
levels of performance and are not intended to replace national standards, but to provide a standardized
framework to facilitate the development of national standards. ISO 15928 (all parts) do not provide
design methods and/or design criteria.
Based on the framework provided by the ISO 15928 series, purchasers, regulators and standards writers
in their respective countries can describe their requirements in standardized performance terms, as
appropriate. Additionally, the manufacturers/providers can respond by describing the performance of
their products in a similar manner. The purpose of this document is to provide a standardized system
of describing performance that can be used to specify performance requirements and performance
levels, or to rate houses in terms of accessibility, usability, and safety during use.
The intent is to provide a standardized system that is to be used to realize performance description.
The objectives of this document are as follows:
a) to facilitate international trade in housing systems and housing products and to exchange housing
information and knowledge by eliminating technical barriers;
b) to facilitate innovation in housing by providing a systematic framework for evaluation and
acceptance;
c) to establish user needs related to in specific technical engineering terms in order to facilitate
communication among all stakeholders.
This document can also be useful in increasing consumer product awareness and in developing quality
systems for houses.
NOTE Annex A provides a commentary on this document.

Houses — Description of performance —
Part 7:
Accessibility and usability
1 Scope
This document sets out a method for describing the performance of houses. It covers user needs,
provides performance descriptions, and outlines evaluation processes. It includes the description of
relevant parameters necessary to ensure accessibility and usability in houses. It also includes features
to ensure safety during daily use, i.e., reasonable consideration to prevent accident like tripping, falls,
or collision.
This document is intended for use in the evaluation of the design and construction of houses, in the
international trading of houses or their sub-systems, and in developing risk-management tools
